The Spline Editor provides a
tabular or
plot view of your spline data for editing and plotting. You can drag points on your spline plots and see the effect of different curve-fitting techniques on your spline. You can also select linear extrapolation and view its effect.
Using the Spline Editor, you can create a two- or three-dimensional splines. Note, however, that the Spline Editor does not display a three-dimensional spline in plot view.
To set the view of the Spline Editor:
